Public Health: CDC
• …the science of protecting and
improving the health of people and
their communities… achieved by
promoting healthy lifestyles,

Behavioral Medicine
“The development and integration of
biomedical, psychosocial and
behavioral sciences’ knowledge and
techniques and the application of this
knowledge and these techniques to
prevention, diagnosis, treatment and
rehabilitation.”

Behavioral Medicine Challenges
• How does “behavior” contribute directly
or indirectly to regulatory processes?
• How does the variability of functional
state (“reactivity”) affect disease
processes?
• What are the interactions between
stress and other risk factors that may
promote or inhibit disease processes?

Stress
“…the body’s response to any real or
imagined demand placed upon it.”
- H. Selye, 1946
![Page 19: Behavioral Medicine and Public Health · 2017-11-27 · Behavioral Medicine “The development and integration of biomedical, psychosocial and behavioral sciences’ knowledge and](https://reader033.fdocuments.us/reader033/viewer/2022043003/5f807a2be7986d6d6b15984a/html5/thumbnails/19.jpg)
Stress
• Stress is a physiological response to
some internal or external stimulus
• Stress can be good (“eustress”) or bad
(“distress”)
• Stressors (internal or external stimuli)
are part of our everyday existence
![Page 20: Behavioral Medicine and Public Health · 2017-11-27 · Behavioral Medicine “The development and integration of biomedical, psychosocial and behavioral sciences’ knowledge and](https://reader033.fdocuments.us/reader033/viewer/2022043003/5f807a2be7986d6d6b15984a/html5/thumbnails/20.jpg)
Stress Reactivity
• Reactivity to stress may be determined
by our perceived ability to cope
effectively with the stressor; our
response to stressors typically take the
form of mobilizing the body for “fight or
flight”
![Page 21: Behavioral Medicine and Public Health · 2017-11-27 · Behavioral Medicine “The development and integration of biomedical, psychosocial and behavioral sciences’ knowledge and](https://reader033.fdocuments.us/reader033/viewer/2022043003/5f807a2be7986d6d6b15984a/html5/thumbnails/21.jpg)
The Stress Response
• Liver releases sugars or fats
• Respiration increases
• Red blood cell production increases
• Heart beats faster and blood pressure
rises
• Blood clotting mechanisms are activated
• Salivation and digestion cease
• Perspiration increases
• Pupils dilate
